Question

Promeristem gives rise to which meristem?

• A. Secondary
• B. Lateral
• C. Primary
• D. None of the above

Answer 1

The correct option is C Primary

On the basis of origin and development, meristem is grouped as promeristem, primary and secondary meristem.

Promeristem includes undifferentiated, actively dividing apical initials, which are derived from embryonic tissues and give rise to primary meristem.

Primary meristem is derived from promeristem or embryonic meristem and produce primary permanent tissues of primary plant body.

Secondary meristem develops from permanent tissues during secondary growth and give rise to secondary tissues, for example cork cambium is derived from pericycle or cortex, not from a promeristem

Meristem present at the sides of the plant is termed as lateral meristem. They are derived from primary permanent tissues during secondary growth and cause increase in girth of plant, for example, vascular cambium and cork cambium

So, the correct answer is 'Primary'
